* There is an optional hardcore mode, the character needs to drink water, ammo has weight, healing isn't instant etc. Normal mode is more similar to Fallout 3 gameplay.* The storyline is focused on the New California Republic vs. Caesar's Legion vs. New Vegas residents.* You are not a vault dweller but are given a Pip-Boy by someone who is one.* There is a screenshot of a vault suit as well.* There is an assault rifle looking like the M4, as well as a new big gun with a backpack, held like a minigun.* There are special moves for melee weapons in VATS - specifically a move for a golf club called "Fore" which seems to be a groin shot.* The Hoover Dam is in the game and is supplying electricity to the city.* There is a quest to rescue a ghoul from some super mutants. The ghoul can then become your companion* The Geckos are back.* There are both dumb and intelligent super mutants, including the elite Nightkin.* Some super mutants look similar to the ones in Fallout 3, while others are new. There is e.g. a female super mutant with a 1950s hairstyle who apparently is one of their leaders.* Screenshots include a guy with a beard and straw hat, a ghoul an NCR Ranger* The only picture of New Vegas itself is concept art and not a screenshot* Some location screenshots include a huge model dinosaur advertising a hotel, some satellite dishes, an array of solar panels* A character generation shot showing a "vigour machine" instead of the skill book* NCR base is the McCarran Airport, Caesar's Legion is based in the Vegas Strip, while super mutants are based in a place called Black Mountain. There is also a town called Fremont and another called Primm. A topless reuve is mentioned as being in the latter. Area 51 also appears.* NCR Ranger armor is similar to a brown combat armor with sleeves, there are concept arts of a Ranger* Skils have a bigger effect on conversation choices. E.g. someone with a high Explosives skill may be able to have a coversation about explosives where appropriate.* There is a Reputation system in adition to Karma.

All factions neutural. Respect ratings for each means they have their own ideas of right and wrong, and a single karma factor indicates you can do BAAAD things in general. (killing slaves is bad for business and is creul, but if they are trying to kill you it's okay...)

I think both Kotor 2 and NWN 2 where better then the original games. But i have a very low opinion on NWN so is not that hard to surpass. Kotor 2 had issues but i attributed that to a rushed schedule. I hope there not rushed with FNV. If they are then i bet it will show. It almost always does.
